5 facts about Goldfish pets

  1. 1
    Goldfish are actually a domesticated member of the carp family and can grow up to a foot long if they are kept in a large enough tank or pond instead of a small bowl.
  2. 2
    Goldfish do not have stomachs, so instead of digesting food in a traditional way, they process nutrients as the food passes directly through their intestinal tract.
  3. 3
    Goldfish can recognize their owners' faces and will often swim to the front of the tank to greet them when they walk into the room.
  4. 4
    Many people assume that goldfishes have a three-second memory, but studies have shown they can actually retain memories for months and can even be trained to navigate mazes and recognize their owners.
